DEVICE FOR SECURING TOGETHER SHEET-FILING, 8w.

To all whom it may concern Be it known that I, EMERY H. FAHRNEY, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Devices for Securing Together Sheet-Piling, &c., of which thefollowing is a specification.

This invention relates to improvements in devices for fastening orconnecting sheet pil ing, particularly adapted, though not necessarilylimited in its use, for the construction of caissons, coifer-dams, andthe like, and one of the objects of the invention is to provide animproved device of this class, by means of which'the piling members maybe removably secured together, and which will also form a liquid tightjoint between the respective pile members.

A further object is to provide an improved device of this class, whichmay be readily secured to the pile members.

A further object is to provide an improved device of this class whichwill be simple, durable and cheap in construction, effective andefiicient in operation, and which may be readily attached or secured tothe pile members.

To the attainment of these ends, and the accomplishment of other new anduseful objects, as will appear, the invention consists in the featuresof novelty in substantially the construction, combination andarrangement of the several parts hereinafter more fully described, andclaimed, and shown in the accompanying drawing, illustrating theinvention, and in which Figure 1 is a top plan view, partly in sectionand partly in elevation, showing the manner of connecting together thepile members in accordance with the principles of this invention; Fig. 2is a front elevation partly broken away and partly in section, of someof the parts shown in Fig. 1; Fig. 3 is a de tail perspective view ofone of the connecting members; Fig. 1 is a detail cross sectional viewof a portion of one of the pile members and one of the fastening membersshowing another manner of securing the fastening member to the pilemember.

Referring now particularly to the drawing, and in the presentexemplification of the invention, the fastening device comprises twochannel shaped members designated gen erally by the reference numerals10 and 11. These channel shaped members may be con- Specification ofLetters Patent.

structed of any suitable material, but are preferably constructed ofrolled metal, and may be of any desired width and length. The members 11comprise a body portion, the longitudinal edges 12 of which aredeflected toward each other to form inclined walls, and when sodeflected the fastening members will be of a channel formation. In orderto permit the edges to be readily deflected, the body of the member 11adjacent the edges is shaped so as to be narrower in cross section, asshown. Provided on the back of the member 11 are any number of ribs 14:(in the present exemplification of the invention two are shown), whichare formed integral with the member and extend for the entire length ofthe member. These ribs 14 are pointed or sharpened as shown, and arelocated preferably some dis tance from the lateral edges of the memberwhich edges are formed by the deflected portions 12. The member thusformed may be secured to the pile member 15 in any suitable manner,preferably by means of a fastening device 16 in the form of a bolt whichpasses through the member 11 and also through the pile member. Anynumber of these fastening devices may be provided, and the member 11 maybe provided with the desired number of apertures through which thefastening devices pass. The other and cooperating member 10 of thefastening device is preferably of a width somewhat less than the widthof the member 11, and is provided with deflected portions 17, extendinglaterally beyond the outer face of the member 10. These portions 17 arearranged at an angle with the body portion of the member 10, and areadapted to be inserted into the channel formed by the body of the member11 and the sides 12. Projecting laterally beyond the opposite face ofthe member 10 are ribs 18, similar in construction to the ribs 14 of themember 11, and which extend for substantially the entire length of themember 10. This member 10 is also fastened to one of the pile members 15by means of suitable fastening devices 19, passing through apertures inthe base of the channel formed by th member 10 and sides 17, and alsoengaging the pile member. Themember 10 is provided with straight edges20 arranged at the base of the deflected edges 17 and the width of thechannel member thus formed at the base of the deflected portions 17 isslightly less than the space between the extremities of the deflectedportions 12 of the member 11, so that the members can be connected bylongitudinal movement, and by inserting one end of the member 10 intoone end of the member 11, and may be similarly disconnected. then thesefastening devices are secured to the pile members, one of the members 15may be placed in position, and the next adjacent member connectedthereto by connecting the fastening devices in the manner justdescribed. The body portion of the member 10 extends for some distancebeyond'the extremities of the deflected portions 12 of the member 11,and forms with the cleflected portions 17 a closure for the channel inthe member 11. Likewise the member 11 and the deflected portions form aclosure for the channel in the member 10. When these fastening devicesare secured to the respective pile members, the ribs 1 1 and 18 will beembedded in the adjacent faces of the pile members, thereby prevent ingany liquid from flowing between the pile members and the adjacent facesof the fastening devices. TV hen the parts are thus connected thestraight edges 20 of the member 10 will prevent lateral movement of thetwo fastening devices or members.

In order to cause the adjacent faces of the deflected portions 1217 ofthe fastening devices to form frictional contact, and also preventliquid from flowing between these faces, any suitable means may beprovided which will tend to force the fastening devices away from eachother when they are assembled. For this purpose there may be provided aprotuberance or projection 21 carried by one of the members, preferablythe member 11 within the channel. This projection is provided with aninclined face, and is located preferably adjacent the bottom of themember, so that when the other member of the fastening device istelescoped with the member 11, the lower edge will engage the inclinedfaces of this protuberance or projection, and a further longitudinalmovement of the member 10 with respect to the member 11 will cause thelower portion of the member 10 to be forced outwardly or away from themember 11, thereby forcing the deflected portions 17 and 12 tightlyagainst each other. In order to separate the upper extremities of thesemembers 10 and 11, any suitable means may be provided, which in thepresent exemplification of the invention is shown as a wedge adapted tobe driven between the upper extremities of these fastening members.

Obviously the fastening devices 16--19 may be employed for securinganother fastening device on the opposite edge of the respective pilemember, in which instance the members 16l9 will pass through therespective fastening devices on the opposite faces of the pile member.

WVhcn it is desired to form a caisson or cotter-dam, of angularconfiguration one of the fastening devices may be secured adjacent theface 23 of the pile member, as shown in Fig. 1.

With this improved construction it will be manifest that the pilemembers may be readily connected and disconnected fro-m each other, andafter the parts are assembled, if desired the space between the twomembers 10 and 11 may be filled with any suitable material, such as sandor the like.

In Fig. 4: there is shown another form of securing device by means ofwhich the fastening devices may be attached to the pile member. In thisform of the invention the securing devices 24 are shown in the form ofspikes, which are driven through the apertures in the bottom of thechannel of the fastening members and into the pile member. WVith thisform it will be manifest that the fastening devices may be readilysecured to any form of pile and at any time without the latter beingspecially prepared.

lVhen it is desired to separate the pile member, all that is necessaryis to withdraw the wedge 22 and raise one of the pile members, or moveit longitudinally with respect to the adjacent pile member, when thefastening devices 101l may be readily separated.

The protuberance or projection 21 may be formed separately from therespective channel member and fastened within the member with one ormore suitable fastening devices 21*, which fastening device or devicespass through the protuberance, the bottom of the channel member and intothe body of the pile member.
